# SCC\_CM\_Atten\_Char\_Ind

[Valid for](../../../Shared/FeatureAvailability.md):  CANoe DE • CANoe4SW DE

## Function Syntax

```c theme={null}
void SCC_CM_Atten_Char_Ind ( byte RunId[], byte SourceMacAddress[], byte SourceAddress[], dword NumSounds, dword NumGroups, byte AAG[] )
```

## Description

The callback is called as soon as a **CM\_Atten\_Char.Ind** message is received.

Further details that are transmitted in this request can be queried with the following functions:

* [SCC\_SLAC\_GetApplicationType](../Functions/CAPLfunctionSCCSLACGetApplicationType.md)
* [SCC\_SLAC\_GetSecurityType](../Functions/CAPLfunctionSCCSLACGetSecurityType.md)
* [SCC\_SLAC\_GetSourceId](../Functions/CAPLfunctionSCCSLACGetSourceId.md)
* [SCC\_SLAC\_GetResponseId](../Functions/CAPLfunctionSCCSLACGetResponseId.md)

## Parameters

* **RunId**: Random Run Identifier of sender (8 byte).
* **SourceMacAddress**: MAC address of sender.
* **SourceAddress**: MAC Address of the EV which initiates the SLAC process.
* **NumSounds**: Number of M-Sounds used to generate the ATTEN\_PROFILE.
* **NumGroups**: Number of attenuation groups.
* **AAG**: Average Attenuation Group (array length is indicated by the parameter **NumGroups**).
